I have a need to read large lists of numbers from a file and operate on
them. I tried the following:
read' =do s <- readFile "temp"
print $ sum $ map (fst.head.readDec)(lines s)
But this is quite slow even for 1000 numbers.
Are there any other ways to do it faster? Will it help if a C function does
the reading and Haskell calls that. I have to use Hugs.
Thanks,
Saswat
